Examples of Basic Pandas Operations: Getting Started with Data Frames and Series

Pandas is celebrated for its vast capabilities, but at its heart, it’s built around two core structures: DataFrames and Series. Mastering these basics will pave the way for more advanced data manipulation. Here’s a concise walkthrough of some foundational operations.

Creating a DataFrame from a Dictionary

import pandas as pd

data = {
    'Names': ['Alice', 'Bob', 'Charlie'],
    'Ages': [25, 30, 35],
    'City': ['New York', 'San Francisco', 'Los Angeles']

df = pd.DataFrame(data)


Creating a Series

A Series is essentially a single column from a DataFrame.

s = pd.Series([1, 2, 3, 4, 5])

Selecting Data

To select a column:

names = df['Names']

For multiple columns:

subset = df[['Names', 'City']]

Selecting rows by index:

row = df.loc[0]

Filtering Data

older_than_30 = df[df['Ages'] > 30]

Adding & Dropping Columns

To add a new column:

df['Occupation'] = ['Engineer', 'Doctor', 'Artist']

To drop a column:

df = df.drop('Occupation', axis=1)

Handling Missing Data

df2 = pd.DataFrame({
    'A': [1, 2, 3, np.nan],
    'B': [5, np.nan, 7, 8],
    'C': [9, 10, 11, 12]

# Fill missing data
df_filled = df2.fillna(value=0)

# Drop rows with missing data
df_dropped = df2.dropna()

Aggregation & Grouping

grouped = df.groupby('City').mean()

Merging DataFrames

df1 = pd.DataFrame({'key': ['A', 'B', 'C'], 'value': [1, 2, 3]})
df2 = pd.DataFrame({'key': ['A', 'B', 'D'], 'value': [4, 5, 6]})

merged = pd.merge(df1, df2, on='key', how='outer')

Reading & Writing Data

Reading from a CSV file:

df_from_csv = pd.read_csv('filename.csv')

Writing to a CSV file:

df.to_csv('output.csv', index=False)

Diving into these operations will build a strong foundation in Pandas. With these tools under your belt, you’re set to explore the vast and powerful realm of data analysis this library offers.

Are There Alternatives to Pip?: Exploring Other Installation Methods

Absolutely! While pip is the most widely used package installer for Python, there are several other methods and tools available for installing Python packages. Here’s an exploration of some of these alternatives:
